Application filed December21, 1926 Serial r... 156,098,

My invention refers to improvements in concrete reenforcement, and relatesparticularlyto means for reenforcing the concrete adjacent to or surrounding a beam, column, or other" structural member.

and many andvarious forms of the same gen eral kind are known andused, as shown by patents of- Reed '#1,1 66,545 and Masten #1304586. 7 f I The objects in view in the present invention are to providea simple and eflicient form ofclip formed of a wire or rod, bent at certain predetermined points alternately in opposite directions, without closed looping, for surrounding engagement with a structural beam, column, or the like.

.The clip is generally U-shaped, bentat the end or at each side to provide two spaced apart inwardly extending bearing projections for contact with the beam or column flanges, corner open sided loops, and an intervening outwardly spaced reenforcing bar or strand, with freely extended ends for holding engagement with the structural member.

Certain preferred embodiments of the invention are shown in the accompanying drawings, in which:

Fig. 1 is a perspective View showing th device as applied to a beam; 1

Fig. 2 is a similar view showing the rela tive arrangement of a plurality of the clips, with their supported reenforcing members;

Fig. 3 is a plan View, showing the application of the clip to a column; I Fig. 4 is a similar view showing a modified construction; 1 Fig; 5 is a perspective view further showing the application to a column, in alternating side placement; 7

I Fig. 6 is a view similar to Fig. 3, showing a modified construction.

The structural member, of I-beam, channel, or other similar or compound forms, is

usually provided with a web2 and flanges 3.

The clip member is formed of a rod or wire having parallel sides 4 of suitable length for binding around or over'the flanges, with a cross connecting member 5 having inwardly bent open loops or reversed bends 6. These are preferably located adjacent the side The practice of concrete reenforcement is well established and understood by those skilled. in the art,

members 4 which arebent inwardly, as at 7 forming outwardly bent openloops on the same general plane 'as connecting member7.

As thus made the clip is adapted to i'be V I placed around the beam, einbracing itat each slde, so that the free endsmay be bent overthe outside 'of'the upper' fianges, for

secure attachment, as in Fig. 1. In'such position the inwa'rdly deflected shoulders 6'bear against the outer face of the opposite flanges, 'spaclng-tliecross'arm 5 and theopen'loops'i outwardly'from contact, and in' projecting location for "encompassing embodiment 1n adjacent surrounding concrete A, as" shown.-

By such arrangement the open loops 7 provlde projecting stirrup supports for loosely placed longitudinal reenforcing strand members, as wires or. rods 8. These latter are also I supported in such manner materially below the lower face of the beam, for complete im-. mersion and imbedding in the concrete, away from the beams. 'Such longitudinal strands or rods, being at the corner portions of the structural member, tendto avoid cracking of the concrete at-such locations. In making the clip for use on a column, as in Fig.3, the end connecting cross member 9 is preferably straight, as shown, for bridging across the edges of the flanges 3, leaving ample space for the surrounding concrete A. The side members 4 in such case are bent inward-1y, as at 6, with the outwardly spaced connecting arm 5, similar to the construction already described. When the freeends of the strands 4 are bent around the column in opposite directions, open loops 7 like loops 7 are provided, one at each corner, for placement. of the longitudinal vertical reenforcing strands 8. These may be tied in place by light wiring or otherwise, if desired.

I The clips are preferably applied from alternately opposite sides to the column for better averaging thestrain resisting reenforcement throughout the length of the column.

If desired, the free arms of the clips may be sufficiently long to bend entirely'around the opposite side of the beam or column, as

indicatedin Figs. 1 and 3, or they may be 7 made shorter, for clinching attachment arplund the adjacent flanges, as in Figs. 4 an 5. r 7

maybe easilyapplied and held in place and Will not only provide ample projectinganchoring elements for the concrete, but also ensure the supporting and holding placement of the longitudinal strands. outwardly from the structural member.

It Willalsobe observedthat the-cross arm 5 or 5 may'beused. as a support. orbrace for additional:longitudinalmembers 8 or 8, should suchubedesired.

The advantages of the construction Will be readily: understood. and appreciated by all thoseaccustomedlto the use of'concrete reenforcerrient.

. The clips are easily andcheaply formed of straight rods-or Wire and are capable of compact packing, shipment or storage. They may. be located, at any desired spacing distance-apart and arereadilyadapted to quick application and use in the; manner described.

They may be made of any suitable size, gauge or Weight to suitv the conditions of use; and have proved to be highly efficient in the art. I
